Yet more valid points from Walter and I have to agree but to counter that, if those titanium or rhodium plated kits seem to last reasonably well, is it unreasonable to expect all plating's to do so?
If you want Mont Blanc quality you are going to have to pay Mont Blanc prices, While that I suppose has to be correct, I feel justified to expect a rise in quality with the increase in price, that said I take kit 3 from the equation.
There is a marked improvement in quality with those since the supplier took it upon himself to do something about it.
